InglésMycoparasitic antagonism of a Trichoderma harzianum strain isolated from banana plants in Oaxaca, Mexico

Resumen

tropical climate. In Mexico, the banana production has increased, and it must be guaranteed. The Panama disease,
caused by the fungus Fusarium oxysporum f.sp. cubense threatens the current banana production, for what is necessary
to implement methods to protect this crop. Fungi from genus Trichoderma are natural residents of the rhizosphere,
which comprises mycoparasite species used to control diseases caused by phytopathogenic fungi, and also benefit
plant development. Here, we report a novel Trichoderma harzianum strain identified by optical microscopy and by
DNA sequencing of 3 loci. The antagonistic capacity towards causal fungi of Panama disease was demonstrated by in vitro
confrontation assay and co-inoculation in roots of ‘plátano manzano’ plants. Therefore, this fungus can be enabled to
obtain organic formulations for biological control that contribute to produce pathogen-free plants and healthy and high
quality fruits.
